Default soft fiberboard help.... please

Hi all,
I need some “soft Fiberboard” or in German “Weichfaser dammplatte” for some speakers.
Can anyone tell me what to ask for at the hardware store? I need a 13mm (1/2”) variety.
Is it something similar to the yellow fiberglass duct material used for making airconditioning ducts? Does it look like styrofoam? Apparently it has a paper backing on some types.
Thanks
Andrew

It's sometimes called building board in the UK.

Ask for something to make a noticeboard (pinboard).

Hi Andrew,

Here in Canada it's just called fiberboard and is used extensively as an insulation overlay in a roofing system.

Are you using this for damping material? It is not suited for cabinet construction.

You will get it at building supply places that specialize in roofing products, not your average hardware store. It comes in plain and asphalt impregnated. The most common thickness here is 7/16" The paper backing is called a facer.

I imagine its for internal damping of one of Horst's cabinets. He's big on using this stuff on the internals.

hi, i have a question about using damping/lining material such as this or underlay etc.
do any of you try to guestimate the volume of the material used and compensate with the size of the cabinet ?

Greets!

These various fiberboard products are all dense enough that all of it should be accounted for in determining net Vb and if you use any with a facing, it should be against the rigid outer wall panels.

Give Scott the prize

Yup, I am going to try the the Schalmei Sat that Horst designed.
I was also doing some more reading and have found that this material has been in use for many decades apparently in German designed / built horns in both the regular and tar versions. I found some here at the hardware store. Its called Hushboard and it looks to me very similar to mdf that got wet and expanded.

GM, have you ever heard it/ or heard of it used in speakers?

Andrew

I've experimented with it, but it 'sucks the life' out of a well designed speaker IMO, being better suited for limited BW, high Q alignments that need such broadband damping, such as a minimally/non stuffed 'sub' TL.
